condition occur.
condition occur.
The benefit of this backup method is that it is almost non-disruptive.
Prerequisites
You need the following items in place before you start with the procedure:
•
A NFS export on your backup storage preconfigured as rw,no_root_squash. You will mount this
export on the ESXi host. Optionally, adding the async option (async,rw,no_root_squash) can speed
up operation but can put a high load on the NFS machine.

•
The Cisco-modified ghetoVCB.sh script which can be downloaded from
.
•
Root access (SSH) to every ESXi host running your virtual environment.
•
None of your virtual machines should have any snapshots created. Having snapshots will result in
failure to create the backup.
failure to create the backup.
Limitations and Known Issues
This approach has these limitations:
•
None of your virtual machines can have snapshots created.
•
You may loose the latest search indexes. If this happens, reindex all search indexes.
•
The NFS storage used by Cisco WebEx Social roles will not be backed up. It's the customer's
responsibility to back it up as and when appropriate. Cisco recommends that you always back up
your NFS storage at nearly the same time as the Cisco WebEx Social nodes to maintain consistency.

These known issues have been identified:
•
Restored VMs may reboot once the first time they are started. After that start-up should continue
trouble-free.
trouble-free.
•
A file system journal recovery will need to complete following the restored VM’s first boot.
Configuring the Backup
Note
The procedure in this document only creates backups of Cisco WebEx Social nodes that store
irrecoverable data (JSON Store, Analytics Store, RDBMS Store, Director). The rest of the Cisco WebEx
Social nodes do not need to be backed up because they can be simply redeployed and rebuild their data
(if any) based on data from the restored nodes. The steps in
